An ugly duckling problem

The position shown in this week’s main diagram is the starter problem for the Winton British Chess Solving Championship, an annual competition.

Many composed positions have an ugly duckling problem. Practical players are accustomed to discernible pawn structures and an approximate balance of material. An irrational starting position, like this one, is apt to draw a little wince. But look deeper, as there is grace and harmony to be found. Composed problems teem with ingenious and beautiful ideas expressed in ways that you might never encounter in practical play.
